I want to purchase a 1010LT but I'm curious as to how to hook up the output. I am assuming you can configure two of the outputs to feed your speakers, but what about headphones. Will the 1010LT outputs drive a set of headphones or will I need a headphone amp? Or will the 1010LT coexist with another sound card? I'm mainly looking at overdubing. Listening to the mix while adding additional tracks. I will be using Adobe Audition.
